urban expansion model (uem) was adapted to simulate urbanization which implements geospatial information systems (gis), artificial neural networks (anns) and remote sensing (rs). two satellite imageries with specific time interval, socio-economic and environmental variables have been employed in order to simulate urban expansion. socio-economic and environmental variables were used as inputs wh...

This paper examines the positioning accuracy of a GSM beaconbased location system in a metropolitan environment. We explore five factors effecting positioning accuracy: location algorithm choice, scan set size, simultaneous use of cells from different providers, training and testing on different devices, and calibration data density. We collected a 208-hour, 4350Km driving trace of three differ...

This paper examines the relationship between job sprawl and the spatial mismatch between blacks and jobs. Using data from a variety of sources including the U.S. Census and the ZIP Code Business Patterns of the U.S. Department of Commerce, I control extensively for metropolitan area characteristics and other factors.
